'/1TTORNEY Patented July 26, 1932 UNITED STATES THOMAS E. JACKSON, or YOUNGSTOWN, OHIO AUXILIARY AIR, INTAKE AND MIXING DEVICE Application filed July 13,

This invention relates to auxiliary airintake and mixing device for internal combustion motors and particularly relates to devices of this character adapted to be a; clamped between the carburetor and intake manifold.

The principal object of myinvention is to provide a simple and inexpensive device designed to reduce the amount of gas used and at the same time allow enough for energizing the motor. Another object of my invention, is to provide a device which causes the mixture after leaving thecarburetor to be subjected to a dual whirling ortwisting movement, thereby more thoroughly atomizing and mixing the mixture with air before entering the motor.

With the foregoing and other objects in view which will appear as the description 29 proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a top plan view ofthe device. Figure 2 is a side elevation of the device. Figure 3 is a cross sectional view taken on line 3-3 of Figure 1. r

Figure 4 is a cross sectional view taken on line 4-4 of Figure 1.

Figure 5 is a side elevation of the device properly inserted for use.

Figure 6 is an enlarged view of the screen member 15.

In the drawing, 1 indicates a carburetor of any usual construction, 2 indicates a pipe leading from the carburetor to a manifold of usual construction. The carburetor 1 is provided with an ordinary flange 3 and the pipe 2 is provided with an ordinary flange 4: and these flanges are usually secured together by 7 bolts 5, so that a continuous passage from the carburetor to the manifold is formed, by

which the explosive mixture formed in the 1928. Serial No. 292,458.

carburetor is delivered to the manifold and distributed to the engine cylinders.

Between the flanges 8 and 4, I have inserted a plate 6, preferably of sheet metal constructed in such a manner as to cause a circular, twisting motion ofthe explosive mixtureformed in'the carburetor, and at the same time provide means for inlet of air which is introduced into this circular, twisting mixture in a manner so as to strike this explosive mixture in a reversible motion from that of the motion of the explosive mixture formed in the carburetor.

By referring to Figure 1, it will be seen that the plate 6 is provided with openings 7 .5 for the reception of bolts 5, centrally located in the plate 6, there is provided a circular groove 8 provided with a plurality of inlet grooves 9 which connect to an outer edge 10 of the plate 6 and communicate with the an- 7 nular groove 8. Within this annular groove 8, there is provided a plurality of upturned curving and twisting lips 11. It will be seen that each ofthese lips 11 are symmetrical, each having a curved and twisted edge 12 15 and a relatively straight edge 13. It is obvious that when the explosive mixture is caused to flow through the openings formed by the lips 11, this mixture is given a terrific whirling motion'in an anti-clockwise movement. Into this whirling flow of explosive mixture, air is allowed to enter through the grooves 9 which communicate with the annular groove 8 at a point 14 which is centrally located at base of each of the lips 11.

Due to the formation of the lips 11, the edge 13 is relatively lower than the edge 12 and therefore this inlet of air rushing up over the outer surface of the lips 11 encounters the anti-clockwise whirl of the explosive mixture in a clockwise direction.

By referring to Figure 6, it will be seen that I have provided a screen member 15 which is placed within the inlet groove 9 for the purpose of straining the air before thesame enters into the pipe leading into the manifold.

It is obvious that with this extraordinary mixing of air with the explosive mixture, more desirable combustion will be produced in the motor at a reduced consumption of gas.

What I claim is In a device of the class described, the

combination of a relatively thin plate adapted 5 to be inserted between a carburetor and a manifold pipe, a central annular groove in said plate, a plurality of air inlets communi eating from outer edge of said plate to said central annular groove, a plurality of lips formed within said central annular groove,

said lips being curved and symmetrical and each lip being provided with a a similar twisted curved edge, said inlets formed in said plate and leading inwardly to said annular groove and directly back of the base of each of said lips for the purpose of introducing air into a whirling and twisting explosive mixture in an oppositely whirling movement, substantiallyas described.

In testimony whereof I afiix my signature.
